Owing to its physicochemical similarities with gasoline and renewable nature, n-butanol (bio-
butanol) has garnered significant researcher interest. However, the lower atomization and …

In order to improve thermal efficiency of spark ignition (SI) engines, an improved technology
to avoid irregular combustion under high load conditions of high compression ratio SI …

Fuel sprays produce high-velocity, jet-like flows that impart turbulence onto the ambient flow
field. This spray-induced turbulence augments rapid fuel-air mixing, which has a primary …

This study applies particle image velocimetry (PIV) to an optical spark-ignition direct-
injection engine in order to investigate the effects of fuel-injection on in-cylinder flow. Five …

High-speed particle image velocimetry (HSPIV) was applied to an optical spark-ignition
direct-injection engine in order to analyse various turbulent properties of the flow-field. The …

Major design features of high-tumble spark-ignition engines achieving over 40% brake
thermal efficiency include a sub-square combustion chamber, less curved or more “straight” …

The influence of the intake valve lift of two Miller cycles on the in-cylinder flow field inside a
DISI engine is studied experimentally since changes of the engine flow field directly affect …

In a direct-injection (DI) engine, the in-cylinder flow is complex. Fluctuations of DI and in-
cylinder flow, and the relationships between those fluctuations, are considered to affect the …

The turbulent in-cylinder air flow and the unsteady high-pressure fuel injection lead to a
highly transient air fuel mixing process in spark-ignition direct-injection (SIDI) engines, which …

In this work, engine flame topological development was studied to improve the
understanding of flame growth in direct-injection engines, in particular when operated under …
